The X-ray free electron laser (XFEL) project at SPring-8 aims to build an X-ray lasing facility that generates brilliant coherent X-ray beams with wavelength below 0.1nm. The facility consists of… Expand

We construct a bi-linear form on the periods of Calabi-Yau spaces. These are used to obtain the prepotentials around conifold singularities in type-II strings compactified on Calabi-Yau space. The… Expand

A theoretical foundation for a generalization of the elliptic difference Painlev\'e equation to higher dimensions is provided in the framework of birational Weyl group action on the space of point… Expand
